DETAILED DESCRIPTION

According to an embodiment, a wearable device is used to authenticate a user into a user account at a user device of the user. In particular, the wearable device may include a sensor, such as an optical sensor or a pressure sensor, configured to detect whether the wearable device is worn by or is with the user. If so, the wearable device may send a signal, such as a short range wireless signal, Bluetooth Low Energy or the like, to the user device and the user device may authenticate the user based on the signal received from the wearable device.

In an embodiment, the wearable device may include a sensor configured to detect whether the wearable device is worn by the user. When the sensor detects that the wearable device is worn by the user, the wearable device may send a unique signal periodically, such as every five seconds or every 10 seconds. When the sensor detects that the wearable device is taken off or otherwise separated from the user, the wearable device may stop sending the unique signal. Based on whether the unique signal from the wearable device is received, the user device may authenticate the user.

In an embodiment, the sensor of the wearable device may be provided at an inner surface of the wearable device facing the user when the wearable device is worn by the user. The sensor may be an optical sensor configured to detect ambient light level. When the wearable device is worn by the user, the optical sensor may be covered by a body part of the user and may not receive light. When the wearable device is taken off from the user, the optical sensor may be exposed and may receive light. As such, the optical sensor may detect whether the wearable device is worn by the user.

In an embodiment, the sensor of the wearable device may be an actuator, such as a button, which may be depressed when the wearable device is worn by the user and may be released when the wearable device is taken off the user. In another embodiment, the sensor may be a temperature sensor configured to detect a temperature. For example, the temperature sensor may detect a body temperature of the user when the wearable device is worn by the user and may detect ambient temperature of the user when the wearable device is taken off from the user. In still another embodiment, the sensor may be a proximity sensor configured to detect a presence of the user when the wearable device is worn by the user. In yet another embodiment, the sensor may be a pressure sensor or touch sensor configured to detect a pressure force or a touch from the user when the wearable device is worn by the user. Other sensors, such as a gyroscope, accelerometer, and the like, also may be used to detect an orientation and movement of the wearable device to determine whether the wearable device is worn by the user or has been taken off from the user.

In an embodiment, a user may set up the wearable device to be used for user authentication with the user device. The user may designate or associate the wearable device for user authentication with certain accounts of the user. In an embodiment, one wearable device may be used for user authentication of multiple different user accounts. In another embodiment, multiple wearable devices may be used in combination for user authentication of a particular user account. As such, various combinations of wearable devices may be used for user authentication of different user accounts.

In an embodiment, the user device may automatically authenticate the user for a user account without requiring the user to enter credentials, such as passwords or login IDs, when the user device receives the unique signal from the wearable device indicating that the wearable device is still worn by the user. In another embodiment, the user device may require a login credential for the initial login and may keep the user logged in as long as the user device receives the unique signal from the wearable device indicating that the wearable device is still worn by the user. The user device may log the user out of the account when the user device no longer receives the unique signal from the wearable device indicating that the wearable device is no longer worn by the user or is separated from the user. In an embodiment, if the user is logged out and the user device receives the unique signal from the wearable device, the user device may still require the user to provide credentials for logging in. The user device may keep the user logged in thereafter as long as the user device continues to receive the unique wireless signals from the wearable device.

In an embodiment, the wearable device may be a watch type device configured to provide time related information and be worn by the user. In another embodiment, the wearable device may be a jewelry type item, such as a ring, a necklace, a wrist band, and the like. In still another embodiment, the wearable device may be a belt, a neck tie, a tie pin, a collar stay, and any other wearable accessories. In still another embodiment, the wearable may be a clip or a tab configured to be attached to the user or other items carried by the user.

The signal also may carry information related to the wearable device 104, such as type, name, ID, description, specification, and/or status (whether worn by the user) of the wearable device 104.

At step 502, the user device 110 may detect the unique signal emitted from the wearable device 104. For example, the user device 110 may be carried by the user 105 or the user 105 is currently using the user device 110. As such, the user device 110 may be located within the wireless broadcast range of the wearable device 104. At step 504, the user device 110 may register or receive the signal. The user device 110 may analyze the signal from the wearable device 104 and may determine that the signal is from a wearable device for user authentication. The user device 110 may ask the user 105 whether the user 105 would like to register the wireless signal for user authentication. If so, the user 105 may be allowed to designate one or more user accounts which may use the signal for user authentication. For example, the user may associate the wireless signal with user 105's payment account at a payment service provider. As such, the wireless signal may be used to authenticate user for that payment account.

At step 506, the user device 110 may authenticate user 105 for the designated account. For example, the user device 110 may ask for the user's login ID, password, finger-print scan, and the like. When the user 105 is authenticated successfully, the user device 110 may then associate the signals from the wearable device 104 with the designated accounts at step 508. As such, the unique signals from the wearable device 104 may be used to authenticate the user for the designated accounts.

At step 510, the user device 110 may allow the user 105 to select or input authentication settings for the designated accounts with regard to the signals. In particular, the user 105 may customize the authentication process for the designated accounts with regard to whether the unique signals are received by the user device 110, e.g., whether the wearable device 104 is worn by the user 105. For example, if the user device 110 determines that the user 105 is wearing the wearable device 104 based on the signals received from the wearable device 104, the user device 104 may keep the user 105 logged in as long as the user device 110 continues to receive signals from the wearable device indicating that the user 105 is still wearing the wearable device. The user device 110 may log user 105 out after a predetermined amount of time (which can be immediately) if the user device 110 no longer receives the signals from the wearable device 104.

In an embodiment, if the user device 110 detects the signals from the wearable device 104 indicating that the user 105 is wearing the wearable device 104, the user device 110 may automatically authenticate the user 105 or log the user 105 into the designated account without requiring credentials, such as passwords or login IDs. In still another embodiment, if the user device 110 detects the signals from the wearable device 104 indicating that the user 105 is wearing the wearable device 104, the user device 110 may require less credentials for authentication or have less strict security requirements. The user 105 may select and customize how the wearable device 104 may provide different features of user authentication for different user accounts.

In an embodiment, the user device 110 may allow the user to designate a combination of different signals from different wearable devices for a particular account. For example, automatic user authentication may be implemented for a particular account when the user device 110 detects that the user 105 is wearing both a particular ring type wearable device and a particular watch type wearable device. In an embodiment, different combinations of wearable devices may be designated for different authentication requirements. For example, when the user 105 is wearing a particular combination of three wearable devices, the authentication requirement may be less than when the user 105 is wearing two of the three wearable devices.

In an embodiment, one wearable device 104 may be used to provide authentication for multiple of user's accounts. For example, when the user 105 is wearing a particular watch type wearable device 104 a, the user device 110 may keep the user 105 logged in at the user 105's bank account and at the user 105's shopping account. In another embodiment, different types of wearable devices 104 may provide different levels of authentication requirement. For example, wearing a ring-type wearable device 104 c may allow automatic access to an account, while wearing a watch-type wearable device 104 a may still require the user 105 to enter his/her user ID.

At step 512, the user device 110 may confirm set up with the user 105. For example, a notification may be provided on the user device 110 to inform the user 105 that a particular wearable device 104 is now set up for user authentication of a particular user's account. In another example, the output device 240 at the wearable device 104 may confirm the set up by beeping, LED flashing or color change, vibrations, or information display (on a screen). The user device 110 may store and update the authentication settings of various accounts of the user 105 and their respective associated wearable devices. The user device 110 may provide a user interface for the user 105 to update, add, delete, and/or modify the authentication settings related to wearable devices.

FIG. 6 is a flow chart illustrating a method 600 for implementing user authentication via a wearable device according to one embodiment. At step 602, the user device 110 may detect unique signals from a wearable device 104. For example, when the user 105 puts on the wearable device 104, the wearable device 104 may detect the user 105 via sensors 210 and may begin to emit the unique signals. In an embodiment, the wearable device 104 may previously have been registered with the user device 110, such that the wearable device 104 may automatically be paired with the user device 110, e.g., via Bluetooth communication.

At step 604, the user device 110 may determine whether the unique signals are for user authentication. In particular, the user device 110 may check and see if the received unique signals are associated with one or more of the user 105's accounts. If so, the user device 110 also may look up the authentication settings to determine how the unique signals may alter the authentication process for the account. At step 606, the user device 110 may authenticate the user 105 based on the authentication settings for the designated account in view of the detected signals. For example, if the user 105 has not been logged into the account, the user device 110 may log the user 105 in automatically without requiring user credentials in view of the signals received from the wearable device 104. If the user 105 already is logged into the account, the user device 110 may maintain the logged in session in view of the signals received from the wearable device 104.

At step 608, the user device 110 may determine whether the signals from the wearable device 104 are received continuously at the user device 110. For example, the wearable device 104 may emit the signals periodically, e.g., every few seconds. The user device 110 may determine whether the signals are received periodically from the wearable device 104 indicating that the user 104 still is wearing the wearable device 104. If the user device 110 continues to receive the signals from the wearable device 104, the user device 110 may keep the user 105 authenticated at step 610. For example, the user device 110 may keep the user 105 logged in at the account. In another example, the user device 110 may have a lower security requirement or authentication requirement for logging in when the user device 110 continuously receives the signals from the wearable device 104. The process then may go back to step 608 where the user device 110 continues to check whether the signals from the wearable device 104 still are detected at the user device 110.

If the user device 110 stops receiving the signals from the wearable device 104 which indicates that the wearable device is taken off from the user 105 or is separated from the user 105, the user device 110 may log user 105 out of the account or stop authenticating the user 105 immediately or within a certain time period, which may depend on user, system, and/or account settings. In another example, the user device 110 may require higher or stricter authentication requirements when the user 105 is not wearing the wearable device 104.

After the wearable device 104 has been taken off from the user 105, the user device 110 may require that the user 105 provide authentication credentials to log in again even if the wearable device 104 has been put back on the user 105. This may ensure that the wearable device 104 is not worn by another user for the purpose of unauthorized access to the user's account.

By implementing processes 500 and 600, a wearable device 104 may be provided to facilitate easier and safer authentication process for the user 105. In particular, the wearable device 104 may include sensors that may detect whether the wearable device 104 is worn or attached to the user 105. The wearable device 104 may be configured to emit signals indicating that the wearable device 104 is worn by the user 105. Based on the status of the wearable device 104, the user device 110 may allow automatic or easier authentication process for the user's account. The automatic or easier authentication may end once the wearable device 104 is taken off from the user 105 to provide security to the user's account.

In the above embodiments, the wearable device 104 is utilized for authentication into user's accounts at the user device 104. In another embodiment, the wearable device 104 may be utilized for user authentication for access into buildings, areas, events, vehicles, transportation networks, and any location where user authentication is required.
